AIR-CYLINDER-LUBRICATOR SYSTEM Specification of Letters Patent.

Patented May 16, 1916.

Application filed January 28, 1916. Serial No. 74,870.

To all whom it may concern:

' Be it known that we, WALLACE E. DUNK- ERLEY, CHARLEY A. MA'r'rMILLER,and J0- snrrr BRUNKER, citizens of the United States of America,residing at Helena, in the county of Lewis and Clark and State ofMontana, have invented certain new and useful Improvements inAir-CylinderLubricator Systems, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to an air cylinder lubricator system and has forits object'the production of a simple and efficient means for feedinglubricant to an air cylinder in such a manner asto efiiciently lubricatethe entire interior portion of the cylinder.

Another object of this invention is the production of a simple andefficient means for delivering the lubricant to a cylinder and evenlydistributing the lubricant over the interior of the cylinder.

With these and other objects in view, this invention consists of certainnovel coinbinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is a side elevation of themechanism employed in the system comprising the present invention. Fig.2 is a side elevation, partly in section, of the sight feed casings,which are adapted to control the passage of lubricant from thelubricator through the distributing pipes. Fig. 3 is a section taken online 3-3 of Fig. 2.

Referring to the accompanying drawings by numerals it Will be seen thatl designates the lubricator which is connected to the sight feed casing2 by means of the pipe 3, of suitable construction. The casing 2comprises a' pair of sight feed tubes 4 which are connected near theupper ends thereof by means of an integral tube portion 5, as clearlyillustrated in Fig. 2 of the drawings. The sight feed casing 2 isprovided with a projecting neck 6 for the purpose of permitting the sameto be conveniently attached to the pipe 3 by means of a nipple orpacking nut 7.

By carefully considering Figs. 1 and 2 it will be seen that the sightfeed casing 2 is provided with a pair of these depending sight feedtubes 4 which tubes are connected to the T-joints 8 carried by thedistributing pipes 9, a communication being made between the dependingtubes 4 and the T- oints 8 by means of the pipe 10.

A valve stem 11 is threaded in the upper end of each tube 4 and isprovided with a tapering lower end 12 adapted to firmly seat upon thevalve seat 13 formed in the upper end of the tube 4 for controlling thepassage of oil from the lubricator 1 into the distributing pipes 9.

As illustrated, the casing 2 is shown as provided with two dependingtubes 4 for engaging the two distributing pipes 9, but it should beunderstood that any number of tubes and feed pipes may be employed,without departing from the spirit of the invention. Each tube 4 isprovided with a sight opening 14 to permit the amount of lubricantpassing down through the tubes 4 to be readily determined by theoperator. A stopcock 15 is carried by each pipe 9 and is provided with avalve 16 controlled by means of a lever 17 and these pipes 9 communicatewith a main air supply pipe 18 carried by the air reservoir 20. Itshould be further understood that the pipes 9 are in turn connected tothe compression cylinder 21 of the alr'compfessor 22, as clearlyillustrated in Fig. 1 of the drawings by discharging the lubricator intothe cylinders for thoroughly lubricating the cylinders.

The operation of the device is as follows: The lubricant passes from thelubricator 1 down through the pipe 3 and into the casing 2 and thelubricant may then be passed into the desired cylinder of the aircompressor by opening one of the valves 11 and removing the pointed end12 of the valve stem from the valve seat 13. This will permit thelubricant to pass down through the tube 4 and into the pipe 9, whereuponthe valve 16 is opened to permit the passage of the compressed air tothe pipe 9, and the compressed air will catch the drippings of the oilfrom the tube 4 and force the same into the cylinder 21.

From the foregoing description it will be seen that avery simple andefficient system has been produced for lubricating an air compressioncylinder, and that the amount of lubricant passing into the cylinder maybe readily and easily controlled by the operation of the device.

What we claim is 1. In combination with an air compressor, a lubricator,of a reservoir, a sight feed control valve, means for forming acommunica-:

tion between said sight feed controlling valve, said air compressor andsaid reservoir, and means for controlling the passage of compressed airfrom said reservoir to said air compressor for distributing lubricantdischarged from said sight feed valve to said air compressor.

2. In combination with a lubricator, an air compressor, a reservoir, asight feed valve, means for forming a communication between saidlubricator and said sight feed valve, means for forming a communicationbetween said air compressor and sight feed valve, means for controllingthe passage of air from said air compressor, and said sight feed valveadapted to regulate the discharge of lubricant into the path ofcompressed air passing through said reservoir for the purpose oflubrication.

8. In combination with a lubricator, a

voir and through said pipes for distributing l lubricant discharged fromsaid sight feed Valve.

4. In combination with a lubricator,

means to be lubricated, means forming a communication between saidlubricator and means to be lubricated, and means for controlling thepassage through said communicating means for permitting-pressure to bepassed through said communicating means when so desired for conveyingthe lubricant from said lubricator to said means. to be lubricated.

In testimony whereof we hereunto afiix 5 our signatures.
